Captain Apache, a Native American officer in the US Army, is assigned to investigate the mysterious murder of a Native American policeman. During his investigation, he comes across the landowner Griffin, who wants to start a war against the Indians. Griffin's men disguise themselves as Indians and terrorize the town in order to put the Indians on the trail. Griffin's aim is to take over their territories where oil and gold have been found, but Captain Apache wants to prevent this with all his might.
